Question

Is j+j+j+j and j with the power of four equivalent? ​

Answer 1

NO

Explanation:

j+j+j+j

remember multiplication is repeated addition!

j+j+j+j = 4j

THIS IS DIFFERENT! powers are repeated MULTIPLICATION.

j^4 = j to the power of 4 = j * j * j * j, NOT j+j+j+j !!!!!

Answer 2

No, they are not equivalent.

Explanation:

j + j + j + j = 4j

j^4

Let's say j = 2

4j = 8

j^4 = 16
